Default My spark plugs, is this a bad sign?

this is how they look like. NGK IR IFR6T 11. Is this sign of sludge (the brown stuff) it's a 99 with 96k miles on it...

I see nothing wrong. The oil sludge has nothing to do with the combustion chamber.

Do you know if I have to remove the timing cover to get the front valve cover off?

I assume you are going on a sludge hunt, so you don't have to remove the timing cover.

Agree with Salim, your plugs look fine.

Sludge hunt is over. I think I might have low/slight/minimal sludge residues. See pic in other thread...

That's carbon, not sludge.

Yeah, I realized. For some reason, I've panicked lately over the sludge talk and everything I see or hear is automatically sludge!
